Immunoreactive angiotensin I and angiotensin II were found in human urine that was purified on octadecasilylsilica cartridges. The daily excretion of angiotensin I and II in healthy volunteers was 189.00 (SE 38.36) and 17.54 (SE 3.07) pmol/24 h or 148.09 (SE 32.22) and 12.82 (SE 2.34) pmol/L, respectively (n = 12). No circadian rhythm was observed in the excretion patterns of angiotensin I and ...
OBJECTIVE The aims were (1) to quantitate angiotensin I to II conversion on the endothelial surface and at deeper sites in isolated arteries, (2) to assess whether the angiotensin II that is formed at deeper sites is released into the vascular lumen, and (3) to examine whether enzymes other than angiotensin converting enzyme (ACE) are involved in vascular angiotensin I to II conversion. METHO...
Losartan potassium, Valsartan , Telmisartan and Irbesartan are angiotensin-II-receptor antagonists (ARA II) group which used in treatment of hypertension alone or in combination with other drugs mainly Hydrochlorothiazide. RP- HPLC method was developed for the assay of three angiotensin-II-receptor antagonists (ARA-IIs) in presence of Hydrochlorothiazide. The method was performed by reversed ph...
High affinity binding sites for angiotensin II in bovine and rat brain membranes have been identified and characterized using monoiodinated Ile5-angiotensin II of high specific radioactivity. Degradation of labeled and unlabeled peptide by washed brain particulate fractions was prevented by adding glucagon to the final incubation medium and including a proteolytic enzyme inhibitor (phenylmethyl...
The renin-angiotensin system is a far more complex enzymatic cascade than realized previously. Mounting evidence suggests sex-specific differences in the regulation of the renin-angiotensin system and arterial pressure. We examined the hemodynamic responses, angiotensin II receptor subtypes, and angiotensin-converting enzyme 2 gene expression levels after graded doses of angiotensin II in males...

background: there is controversy over the potential benefits/harms of the usage of angiotensin-converting enzyme inhibitors (aceis) or angiotensin receptor blockers (arbs) as regards the postoperative mortality of coronary artery bypass grafting (cabg). this study investigates the correlation between the in-hospital mortality of cabg and the preoperative administration of acei/arb. methods: out...
conclusions the at1r a1166c polymorphism appeared not to be associated with the presence of acs in the population studied. background there are very limited data for iranian populations on the predisposing genetic factors for acute coronary syndrome (acs). results there was no statistical difference in the genotype frequency of patients and healthy subjects with regard to age and gender (p > 0....
Background: Heart failure (HF) is a complex disease that under the control of different physiological systems. Left ventricular mass (LVM) strong predictor HF. The renin-angiotensin system (RAS) may contribute to pathogenesis HF and LVM. Aims: aim this study examine association between RAS genetic variants LVM in cohort Polish patients with Methods: included 401 Two-dimensional M-mode echocardi...
